King Engine Bearings Toyota 3K/4K/(Size +0.75mm) Connecting Rod Bearing Set

King Engine Bearings is well-known for making solid engine components, and this connecting rod bearing set is no exception. If you're rebuilding the engine in your 1968-1979 Toyota Corolla, these bearings are built to handle the job. They are designed for the 3K and 4K engines, and this specific set is 0.75mm undersize, which is important if you've had your crankshaft ground down during a rebuild.

These bearings use a bimetal construction with an aluminum base, a common and reliable material for handling the loads and temperatures found in an engine's rotating assembly. This construction helps ensure consistent oil film support, which is critical for protecting your crankshaft and connecting rods from wear. When you're putting an engine back together, getting the bearing clearances right is key, and using a set like this that's made for the application helps ensure you're on the right track.
